IMPROVEMENT IN LIGHTNING-RODS.

Specification forming part of Letters Patent No. 183,370, dated October17, 1876; application filed April 8, 1876.

To all whom it may concern:

Be it known that 1, ROBERT S. CO E, of Mount Pleasant, in the county-0fHenry and State of Iowa, have invented a new and valuable Improvement inLightning-Rods; and I do hereby declare that the following is a full,clear, and exact description of the construction and operation of thesame, reference being had to the annexed drawings, making a part of thisspecification, and to the letters and figures of reference markedthereon.

Figures 1 and 2 are elevations of the ground-section of my improvedlightning-rod and its sleeve.

My invention relates to improvements in lightning-rods; and it consistsin the peculiar construction of the sleeve which receives thegroundseetion of the rod, said sleeve being provided with openings forthe escape of Water to moisten the ground around its lower end, thusrendering the connection more perfect, the sleeve being also providedwith multiple discharging-points for the conduction of the electricfluid, as will be hereinafter more fully set forth.

In the annexed drawings, 0 is a sleeve, which receives theground-section A of the lightning-rod, the sleeve being provided withopenings 0 0 for the escape of water to moisten the ground, and therebyrender the conduction of the electric fluid more perfect. The openings 0o in the sides of the sleeve are made some distance below its upper end,or

may be made in its bottom, and any desired number may be employed, sothat the rainwatereontained in the sleeve maypass through the openings,and keep the earth about the lower end of the sleeve moistened.v Thissleeve is made of sheet metal, preferably of copper, and it may beeither cylindrical or grooved to correspond with the shape of the rod. DD are discharging projections at the lower end of the sleeve, and alsoover the openings 0 0, by means of which the electricity is dischargedinto the moistened ground.

It will be seen that by attaching the tube O to the ground-section A ofthe rod the former will bepartially filled with water in case of rain,which will flow through the openings 0 0, thus keeping the earth aroundthe sleeve constantly moistened.

What I claim as new, and desire to secure by Letters Patent, is

The sheet-metal sleeve 0, provided with the discharging projections D Don its lower end and sides, and having openings 0 0 in its sides, saidsleeve being adapted to receive the groundsection A of a lightning-rod,substantially as described, and for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

ROBERT S. COLE.
